Perfect timing. I was actually planning on picking up a pair of ciem.

Would love to have iPhone/android cable options.

Yup using it with my nexus 6. Works fine out the box.

[/@]Ludvigrollver Your pm-3 is on its way.

I am interested and I agree to the terms and conditions. Can't wait to pair these cans with my HA-2. Thank You

Thanks. Me and Frank worked it out.

Fiio e18 and Opposed HA-2 both works fine on my nexus 6. Make sure you are using an otg cable

I'm willing to sell my zxr if you want a replacement.

I have to agree with Relic about listening to music at a high decibel level.  I used to listen to loud music all the time when I was younger and now my ears are getting more sensitive it. I have to turn down the volume a bit especially if I am using headphones and IEMs.  Sigh the joy of aging.
